MOP HEAD.

Application filed march 22, 1926. Serial No. 96,531.

My invention relates to mop heads and more particularly to one adaptedfor rever- Sal in a handle stick so that the mo fabric onboth sides ofthe head may be se ectively employed, the principal objectof the presentinvention being to securely but flexibly connect the head with thehandle and provide an improved assembly of the head elements.

,In accomplishing this and other objects of the inventionll haveprovided the improved details of structure, the preferred forms of whichare illustrated in the accompanying drawings, wherein Fig. -l is aperspective view of a mop head and handle, parts being broken away forbetter illustration.

Fig. 2 isan offset longitudinal seetion'on the line 22, Fig. 1.

Fig. 3 is a'disassociated view of the head elements andhandle. v i

Fig. 4 is a detail, disassociated view of thehandleelipand a part ofthehandle.

Beferring more in detail to the drawings:

1 designates an assembled head, preferably pentagonal, with a recess 2in its rear end through which the handle 3 may swing when the head isreversed to present a different face of the mop fabric (not shown) foruse.

In detail construction, the head comprises top and bottom plates 45 ofsheet metal having edge flanges 67, one adapted to telescope within theother when the plates are brought together to form the head, the platesbeing then secured together by eyelets 8, located in pockets 9 formed bycountersinking the plates as illustrated in the drawings.

To provide proper pivotal mounting of the head on the handle, the pivotshould be located. at the center of the head on an elongated axis thatwill hold the head flat to a floor, and in a manner that will prevent atoo free movement of the head relative to the handle. Such a mounting iseffected by means of a clip 10, formed of a sheet metal strip bent uponitself and having longitudinal grooves 11 adjacent its freeedges forseating the handle prongs, having trans- Verse notches 12 at the centersof its free edges, through which the shanks of the ham dle prongs maymove when the head is turned on its pivotal mounting, as will presmay bedescribed, and having a lip 13am one edge of the clip which is turnedback over the other edge ofthe clip when the par-ts are assembled, tohold the clip .to the handle prongs.

The ;clip 10 is located between the body plates 4 5, at the base of thehandle recess 2, with the free edges directed rearwardly,

plates 15 and the flange 15 are cut away to form the openim 16 inregistration with the notches 1 2 in t 1e clip, for accommodation of theshanks of the handleprongs.

,The handlemember comprises the stick element, a ferrule 17, and a prongelement consisting of a piece of spring wire 18 .extending from a top 19on-the end of the handle and bent upon itself to form the shanks 20 andlaterally directed prongs 21,which latter are bent laterallyand upwardlyfor the purpose presently described.

In assembling the parts, constructed as described, the body plates arestamped to form the edge flanges, the rivet and clip countersinks, theshank notches and the keeper lip. the clip countersinks embodyingtransverse grooves 22 for receiving the ribs on the clip ormed by thepressing in of the prong grooves 11. The clip is likewise formed bystamping to form the prong grooves, the shank notches and keeper lip,and the blank bent to the V shape illustrated :in Fig. 4.

The first step of assembly is of the clip on the handle prongs. This isaccomplished by setting the clip in a die, locating the handle prongsover the grooves in the lower member of the clip and pressing the topmember downwardly onto the upwardly inclined prongs, spring the prongsto alignment within the clip grooves and finally turning up the keeperflange to lock the clip closed against the tension of the prongs. Thelower head plate is then placed in a die, the clip laid in thecountersink (Fig. 3), and the top plate pressed home, the die formingthe countersinks that press the plates over the clip, forming the ribsover the clip ribs, forming the eyelet countersinks and setting theeyelets. The head is thus formed and the fabric covering applied.

In using the mop the head will pivot on the handle shanks when pressureis applied to permit the head to he moved flatwise over a floor, butwill not turn loosely because of friction of the compressed springprongs intheir grooves, the tension being sufficient to hold the head inset position, but not so great as to interfere with adjustment of thehead or its reversal when it is desired to present an opposite fabricface for use.

lVhat I claim and desire to secure by Letters Patent is p 1. A mop headcomprising separate plate members, a clip interposed between the platemembers, including prong bearings arranged longitudinally of the clipand spaced centrally thereof and of the plate members, and meanspermanently connecting the plate members and clip to form the head.

2. A mop head comprising separate plate members and a clip connected toform the head, the clip being arranged transversely between the platemembers and having spaced prong bearings, the plate members beingrecessed in line with the space between the prong bearings to permitreversal of the head when connected to the shanks ot' prongs mounted insaid bearings.

3. A mop head comprising separate plate members and a clip, the clipcomposed of a folded strip of sheet metal, having opposed groovesadjacent its side edges, and the edge of said clip being notched toseparate the grooved portions into separate prong bearings, the clipbeing secured to said plates and the plates notched in line with theclip notches, whereby handle shanks may project through the notches andpron s on said shanks may have mounting in said hearings to permit thehead to pivot on said prongs.

4. A mop head comprising separate plate members, recessed at the rear toabout their longitudinal centers and countersunk to form inwardly offsetportions adjacent the bases of said recesses and notched at the centersof said plate members, a clip interposed between said plates, havingtransversely extending bearings, spaced in align ment with the platenotches, and means permanently connecting the plates and fixing the cliptherebetween.

5. In combination with a mop handle comprising spring wire shanks havinglaterally turned end prongs bent out of longitudinal alignment, a clipcomprising a strip of sheet metal having grooves adjacent opposite edgesthereof and having notches intersecting the grooves, the strip beingbent upon itself to register the grooves and notches and upon the prongsto align the prongs within the bearings formed by said grooves, a keeperlip on one edge of the clip overlying the other edge thereof to hold theparts together against the tension of said prongs, body plates enclosingthe clip and having handle shank notches, and means permanentlyconnecting the plates and the clip.

In testimony whereof I afiix my signature.

HERBERT M. STURGIS.
